What will come in the place of the question mark ‘(?)’ in the following equation, if ‘−’ and‘÷’ are interchanged and ‘×’ and ‘+’ are interchanged?

7 + 45 − 15 × 5 ÷ 12 = ?​​

Given: 7 + 45 − 15 × 5 ÷ 12 = ?

​Given equation is solve by BODMAS rule.

New equation:  7 × 45 ÷ 15 + 5 - 12 = ?

7 × 3 + 5 - 12 = ?

21 + 5 - 12 = ?

26 - 12 = ?

? = 14

Thus, correct option is (a).
